This is an effort to make ppt of p block elements , a topic in XII, chemistry(cbse) , whom as a tutor i have often felt students are horrified due to its large text size, long descriptipns, several information to be remembered and several reasonings to keep in mind.
Hope this ppt would solve thier problem of a thorough preparation of topic with all important aspects covered in the ppt.

Die Seele der Steine von Firos Holterman ten Hove (Leseprobe)Josef Ries
Das Naturreich der Mineralien und seine Bedeutung für uns
Mensch und Stein haben große Ähnlichkeiten und enorme Unterschiede. Beide drücken die ganze Vielfalt der Schöpfung aus. Aber wo der Stein dies tut in einer Art von Tiefschlaf, entdeckt der Mensch sich als Ausdruck der Vielfalt nicht nur im Mineralreich, sondern auch im Pflanzen- und Tierreich.
Wir Menschen haben den ganzen Kosmos in uns, sagt Hazrat Inayat Khan. Als einzelne Wesen sind wir durch die Naturreiche mit ihren verschiedenen Bewusstseinsstufen gegangen. Wir haben in unserem Wesen einen mineralischen Aspekt, einen pflanzlichen und einen tierischen. Und somit sind wir jeweils ein Kosmos in Miniatur.
„Als ich von Firos Holterman ten Hove das Manuskript dieses Buches erhielt, war es für mich absolut erfrischend, einmal Inspirationen zu den Steinen und ihrer Heilkraft aus einer ganz anderen Quelle zu bekommen. Vieles davon bestätigt auch mein Erleben der Steine, anderes bringt wertvolle neue Gesichtspunkte hinzu. Von daher möchte ich das Buch sehr gerne empfehlen.“
Michael Gienger, Gründer der analytischen Steinheilkunde, Buchautor.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

4. • Double bond stability and katenasi's character
Double bond on oxygen much greater than its single bond, single bond
O-O is very weak relevance with formation katenasi. In carbon groups
(faction 14), katenasi’s ability is decrease with its increasing atomic
number, but in groups 16, Sulfur can form the longest chain (S8). In
fact, single bond O-O is weakest than single bond of oxygen atom with
other atoms, O - X. Thus, oxygen atom prefers to form bonding with
another atoms than with itself.
• Its absents orbital d.
Oxygen forms just one with fluorin's compound which is OF2, but sulfur
can form some compound with fluorin include SF6. To reach until six its
covalent bonds, sulfur atom have to involve orbital d. Thus, not be found
flourin's oxygen compound that analog with SF6 because there is no
orbital d in oxygen atom.
